, Application filed June 24,

To all whom it may concern:

Be it known that we, WILLIAM L. Romn- SON and WILLIAM E. G. ROBINSON, citizens of the United States, residing at Concord, in the county of Cabarrus, State of North larolina, have invented a new and useful Spindle, of which theiollowing is a specification.

This invention relates to an improvement in spindles for spinning machines.

The primary object of the invention is to so construct a spindle and its supporting mechanism as to reduce friction, the various parts of the supporting mechanism being such that the same may readily be replaced when they become worn.

In the, drawings :Figure 1 is aview in elevation of the spindle and its supporting mechanism removed from the rail base. Fig. 2 is a similar view, the bolster and sup porting mechanism being shown in section. Fig. 3 is a sectional view showing the mechanism positioned withina bolster case.

In the drawings 10 designates the spindle, the tapered pintle of which extends within the tapered. bore of a bolster 11 which is seated in the bolster case 11 the case being fixed with respect to the bolster as shown in Fig. 3 of the drawings or in any suitable manner. bolster and its end port-ion 11 vis tapered and is supported by a socket 153 which forms a continuation of the bolster 11, this socket being formed with the bore 12 and the tapered seat 12". The socket is provided with a reduced extension 13, the end of which is dished to form a seat for a. ball 14. This ball is supported by a base member .15 which is formed with an extension 16 similar to the extension 14, the two extensions 13 and 15' being so constructed as to prevent the displacement of the ball 14. It will be noted from the foregoing that this peculiar mounting of the spindle provides a support which greatly reduces friction, it

being noted. that when the parts becomedry from lack n oil, binding is absolutely prevented, the ball bearing and the support for the end of the pintle being in alinement, the spindle thus being allowed to revolve freely.

Particular attention is called to the peculiar construction and arrangement of the Specification of Letters Patent.

The pintle extends beyond the Patented Sept. 3, 1912. 1911. Serial No. 635,057.

members 12 and 15, the three members which supportthe spindle, that is the sleeve or bolster 10, and the members 12 and 15, b e-- ing readily replaced should the same be: i

come worn, each part being easily removed from the others.

It will be noted that whenthe s indle becomes dry, the absence ofoil may be readily detected by reason of the peculiar constructed support,- the spindle turning freely is dry. u

The many advantages of a support of this character are elearlyapparent as it will be ing mechanism may be easily and cheaply manufactured, and that said supporting mechanism may be readily assembled.

hat is claimed is 1. In a spindle support, a tapered bolster spindle, said pintle extending beyond said bolster, a sleeve arranged on the end of said pint-1e, said sleeve being formed with an extension, the face of which is concaved, a base member, said base member being provided with an extension, the end portion of which is concaved and a ball arranged between said extensions.

2. In a spindle support, a tapered bolsterfixedly mounted in the bolster case-and arranged to receive the tapered pintle of the spindle, said pintle extending beyond said bolster, a sleeve receiving the end of said pint-1e, said end being tapered, the sleeve being formed with a seat to receive said tapered end, said sleeve and bolster being coterminous, said sleeve being formed with an extension the face of which is concaved, a base member, said base member being provided with an extension the end portion of which is concaved, and a ball arranged between said extensions.

In testimony that we claim the foregoing as our own, we havehereto aflixed our signatures in the presence of two witnesses.
